ROLLER For. sKATns.

Original application filed January 14, 1922, Serial No. 529,232. Divided and this application filed February 28, 1923.

. To 'all w/wm t may concern v Be it known that I, THnoDoRE FEDuN, a citizen of Poland, residing `aty Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in a Roller for Skates, of which the following is a specification.

This invention relates to roller skates and is a division of my Patent No. 1,466,864, issued to me September 4, 1923, and the primary object of the invention is to provide an improved ball bearing roller, which can be readily removed from its mounting when so desired, so as to facilitate the repairing thereof.

A further object of the invention is to provide an improved ball bearing roller, which can be readily taken apart, so that a new tread or wear portion can be interchanged for a worn tread, and thus eliminate the necessity of discarding the whole roller whenonly the tread thereof is worn.

A further objed of the invention is to provide an improved skate roller embodying a resilient body portion and a resilient wear or tread portion and means for supporting the resilient body and tread portion and for connecting the same with a ball bearing race.

A still further object of the invention is to provide an improved ball bea-ring skate roller of t-he above character, which will be durable and eiiicient in use, one which will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

With these and other objects in view the invention consists in, the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this speciiication, in which drawings:

Figure 1 is a side elevation of the improved roller, showing the same connected to a roller mounting.

Figure 2 is a transverse section thereof taken on the line 2-2 of Figure 1.

Figure S is a section through the improvedl roller taken on the line 3-3 of Figure 2.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indi-l Serial No. 621,900.

vcates the improved skate roller and B the mounting therefor.

The mounting B is preferably of the type disclosed in my patent heretofore nientioned and will not be described in detail herein.

The improved roller A comprises a frame made up of a pair of disks 5 and 6 preferably formed of metal possessing the desired tensile strength for the purpose intended and 'each of these disks has its outer end equipped with a laterally extending annular flange 7. Each disk is also equipped with a central, enlarged opening, 8, which is surrounded by a laterally extending annular flange 9. These two disks provide a rigid frame for a rubber roller, which includes a disk-shaped body and a tread portion 11 enlarged laterally to each side thereof, so that when the body 10 is clamped between the two frame disks 5 and 6, the tread 11 will be supported upon the annular flanges 7 of the two frame disks. y This rubber roller and the two lframe disks 5 and 6 are provided with aligned apertures 12 disposed in annular formation for the reception o-f clamping bolts 13, which efficiently clamp the frame disks in engagement with the body of the roller. It is to be also noted that the apertures in the body portion 10 on the rubber roller are equipped with metallic sleeves 14 which form wear surfaces.

It is to be also noted that the central opening of the roller disk, which receives a portion of the axle bolt 15, which is supported by the roller mounting is considerably smaller in diameter than the central openings formed in the frame disks 5 and 6, so as to provide means for retaining cup ball bearing races spaced apart. Each ball bearing race consists of a sleeve-like bearing 16, which is adapted to be clamped in fixed relation to the axle 15. Ball bearings 1S are retained in contact with the bearings 17 by means of housings or shells 19 which are adapted 'to be snugly received in the iiange central openings of the frame disks 5 and 6, with their inner ends abutting opposite sides of the body 10 of the rubber roller. The relative outer ends of the housing 19 of the ball bearing races are curved inwardly toward the center thereof to form flanges to prevent displacement of the ball bearings.

From the foregoing description, it can be seen that an improved ball bearing skate roller' has been provided which can be readily taken apart when so desired, and which will be exceptionally eflicient in use, and which is of a simple and durable construction.

Changes in details may be made without departing from the spirit or Jthe scope of this invention.

What I claim as new is: 4

As a new article of manufacture, a roller for skates comprising a pair of spaced annular reinforcing rigid frame plates, alaterally extending flange formed on the outer periphery of each reinforcing rigid frame plate and a laterally extending flange formed on the inner periphery of each reinforcing rigid 4frame plate, the flanges being disposed in spaced parallel relation to one another, a

resilient member including a disk-shaped body portion disposed between the annular reinforcing plates and extending inwardly of the laterally extending flanges formed on the inner peripheries of theplate and having an axial opening formed therein, an integral tread extending laterally on the opposite sides of the body portion engaging the outer surface of the laterally extending flanges formed on the outer periphery of the `frame plates, and a ball bearing race fitted against the bodyportion of the resilient member and the inner surface of the laterally extending flanges formed on the inner periphery of the frame plates.

In testimony whereof I afix my signature in presence of two witnesses.l

THEODORE FEDUN.
